Yes, it packages a set of code-lines together which have the shared property that they all serve the same purpose. Even if it is called from only one location it makes sense EVEN THOUGH IT DOES NOT REDUCE the code-size. It does the opposite if you call it only once. But it makes it easier to understand the code because it hides details under a separate method. It makes it easier to read the calling code because it makes the calling code shorter. I'm not quite sure however if this was the reasoning behind Intention Revealing Selector which I thought was more about how to name methods, not about whether and when to package multiple method-calls into a single new method.
